yes indeed it is. I tried it again:

GTA02v6 # fatls mmc 0
  1852056   uimage.bin

1 file(s), 0 dir(s)

GTA02v6 # ext2ls mmc 1
Failed to mount ext2 filesystem...
** Bad ext2 partition or disk - mmc 1:1 **

So the fvat partition seems to be vailid, but something is wrong with
the second partition!
Could it be possible that the new mkfs.ext2 commad on my debian sid
writes an ext2 which cannot be read by u-boot veteran of 2008?

I there a known problem with µSD cards and ext2? This SD-card has been
